Unions and Investment in British Manufacturing Industry.

This paper is concerned with the impact of unions on the investment rate in British industry.

However, once we allow for union effects on wages and productivity, this overall effect is reduced to between 4 and 13 percent, depending on the degree of competition in the product market
